Fire Breath is almost always taken
inertial reduction is an always since I normally don't bother with a travel pool with my kinetics. (Maybe tp target)
If you have enough recharge in your rez, you don't need defense. 😉 (normally this is for my blasters, melee tend to actually be tough enough to not need rez)
With the change to repulsion field toggles, their a bit more interesting.
I find PFF handy
Of course, I think the characters in regards to this, most don't have the fighting pool. Granted, I tend to go with the fighting pool for my agro magnets and manuevers with my other chars since that tends to help the actual agro magnets.
